Justin Drake Outlines Ethereum’s Move to SHA/BLAKE

Ethereum is poised to advance its cryptographic framework by dropping Poseidon in favor of more traditional hash functions, SHA and BLAKE. This move, reported by CryptoTwitter commentator @WuBlockchain, highlights a significant evolution in Ethereum’s security strategy. The transition aligns with broader industry goals focused on quantum safety and privacy, indicating a future where Ethereum remains competitive in a rapidly changing blockchain landscape.

The Key Development

As the crypto market continues to exhibit mixed signals, Ethereum’s strategic decisions are garnering attention. The shift to SHA or BLAKE from Poseidon aims to utilize traditional hash functions for enhanced efficiency in SNARK-based zero-knowledge proofs. Justin Drake, an Ethereum Foundation researcher, emphasized that this change reflects advancements in binary-field SNARKs, which reduce the need for specialized hashes. This strategic evolution is expected to culminate in a production-grade leanVM by 2027, followed by widespread deployment across Ethereum’s layers.
